Bpeciiication of Letters atent.

Patented Sept. 17, 1907.

To all whom it may concern.'

Be it known that we, ANDREW M. ANDERSON and lCoizNnLrUs QUEsN-ELL, citizens ot the United States,

.Wheel, of which the following is a specification.

This invention relates to traction Wheels for use in connection 'with agricultural machines and such as are employed for driving the mechanism oi the machine. 4

The object of 'the invention is to provide a wheel of durable construction which is provided with means' whereby lateral slipping is prevented and whereby s'aid Wheel is prevented from slipping in the direction of its movement.

` A still further object is to provide novel means for connecting the drive sprocket or gear to the wheel.

With the above and other objects inview 'the invention consists oi a hub to which is connected a rim made up of rings angular in cross section and connected by angular vties which serve to prevent the Wheel fromslipping in the plane of its movement.

The angular vrings constituting the rim are so dis.

posed that a broad flat face is formed along the outer portion of the rim while an angular ilange is arranged around the inner portion of said rim, said flange and face serving to coperate to prevent lateral slipping of the wheel by engaging the surface of the ground. The drive sprocket or gear engages one end of the hub and the periphery of this gear is attached to the riI'n of the wheel by tangentially arranged rods which serve to direct the pressure directly from the rim of y the wheel to the rim of the sprocket or gear.

The invention also consists ofrcertain other novel features of construction and combinations of parts which will be hereinafter more fully described and pointed out in the claims.

In the accompanying drawings is shown the preferred form 'of the invention. In said drawings: Figure-1 is an elevation of the wheel; Fig. 2 -is a transverse'ection therethrough; and Fig. 3 is 'an elevation of a portion of a rim showing the side opposite to that illustrated in Fig. l.

Referring to the figures bycharactersof reference, 1

is a' ring 4having an inwardly extending iiange 2 at suitable securing means. A hub8 extends through `thelcenters of the rings and has enlarged sockets 9 at the ends thereof into which extend spokes l0 which radiate therefrom and are suitably fastened to the 'rings 1 and 3. The spokes from .each socket are secured'only to the ring at the same side of the wheel.

A sprocket or gear Il is arranged upon the inner portion of the wheel and has a boss 12 at the center thereof which projects into the inner socket 9. The spokes 13 of this sprocket are disposed substantially at a tangent to the boss l2 so that the strain is transmitted directly from the center of the sprocket to the rim thereof and substantially in the direction loi the line of draft. In order that the strain may be transmitted directly from the rim of the Wheel to the rim of thesprocket 11, rods 14 are connected atregular intervalsto the rim of the gear or sprocket Vl1 andere disposed at tangente to said rim and fastened to the inner ring 3. By fitting the' boss 12 in one of the sockets of the hub it becomes unnecessary to use any fastening means other than the spokes 13 because said spokes will serve notonly to transmit the strain from the sprocket` to the rim of the .Wheel but will also clamp the sprocket against the hub of the wheel`. vItis thought that the advantages of this construction will be `clearly apparent to those versed in this art. When the Wheel is rotated the flanges of the ties 5 will bite intothe ground and prevent the Wheel from slipping in the plane of its movement. Should the wheel be upon the side of a hill or other incline the inner flange 4 will engage the soil and prevent lateral movement and this holding action of said flange will be assisted bytheiiange 2 which constitutes an abutment against which the soil will press. Although the Wheel may be of considerable size it will be comparatively light because oi the fact that a solid rim is 'not employed. Not only is the wheel very durable in construction but by disposing the spokes in the manner shown the draft is transmitted directly from the rim of' the wheel to the rim of the sprocket or gear 11 and there is no danger of the parts of the wheel becoming twisted. l

The preferred form oi the invention has been set forth in the foregoing'descri'ption but we do not limit i .wardly extending annular flange upon the outer ledge ot onering, an outwardly extending annularan'ge upon the outer edge of the other ring, and ties connecting the rings.

2. A wheel of the character described comprising a hub, rings concentric therewith and secured thereto, an inwardly extending annular ilange uponV the outer edge oi. one ring, an. outwardly extending annular flange upon the outer edge of thc other ring, and diagonally arranged ties connectingthe rings, each tielhaviug an outwardly extending flange.

2i. A wheel of the character described comprising a hui),

rings concentric therewith and secured thereto, 'an inwardly extending annular flange upon thel outer edge of one ring, an outwardly extending annular ilange upon the outer edge of the other ring, diagonally arranged ties connecting the rings, each tic having an outwardly extending flange, and brace strips connecting the rings.

4. In a wheel of the character described the combination ywith a huh having enlarged sockets at the ends thereof; of rings surrounding the hub and' concentric therewith, means for connecting the inner socket and ring, means ior connecting the. outer' socket and' ring, an exterior annular 'flange at the outer cdge o6 the inner ring, an interior annular flange at the outer edge of the outer ring, and means foi-rigidly connecting the rings.

in a wheel of the character describedthe combination witha huh liavingteniarged' sockets at the ends thereof: oi rings surrounding the hub and concentric therewith, means for connecting the inner socket and ring, means for connecting the outer socket and ring, an

exterior annular flange at the outer edge of the inner ring, an interlorannular flange at the outer edge ,of the outer' ring, and diagonally disposed ties rigidly connecting the rings .and having outwardly 'extendingV flanges.

6. A wheelA of the character described comprising a hub rings concentric therewith'and secured thereto, diagonally disposed angular ties upon the outer face of and connecting the rings, said ties outstanding from the rings and having straight edges disposed to engage the lground, and brace strips secured upon the inner. face of the ring, and connecting said-rings.

7. In a wheel ot the character described the combination with Va huh having an enlarged socket at one end, and a rim; of a drive gear, a boss at the center thereof seated within the socket, and-a plurality of regularly disposed tangential connecting rods secured to the rim ofl the gear and to the rim of the wheel.

in testimony that we claim the foregoing; as our own,

'we have hereto aillxed oursignatures in the presence of two witnesses.
